Having survived a European massacre years before that claimed his wife and son, Stephen takes immense pleasure in philanthropic work at a community service center in the U.S. while Esther entertains returning soldiers in a canteen. At the canteen, Esther meets Robert Graham, who because of a war wound suffers from fainting spells, and he falls in love with her. William Morris, a brilliant Jewish surgeon also courts Esther; and the men vie for her affection. When Graham loses control of his car due to a fainting spell suffering grave injury, Morris is the only person who can save his life.
